SIPHON-BOTTLE.

' SPECIFICATION forming part of Letters Patent lIo. 361,400, dated April19, 1887.

Application filed May 6, 1886. Serial No. 201,366. (No model.)

To all whom it may concern:

- Be it known that I, CHARLES DE QUILL- FELDT,a citizen of the UnitedStates, and a resident of New York, in the county and State of New York,have invented a new and useful Improvement in-Siphon-Bottles, of whichthe following is a specification. 7

The invention relates to the top or valve mechanism of so-calledsiphon-bottles, or such as are used for carbonated mineral waters, inwhich the pressure of the carbonic-acid gas with which the beverage ischarged is the means by which the liquid is expelled through the spoutwhen the valve is opened.

The invention comprises improvements in thefollowing respects: theconstruction and combination-of parts, whereby, when the valve is open,direct communication is formed with the spout without an intermediatevertical channel, while at the sametime the packing around the valvestemis pressed tightly aron nd the same, so as to cause no leakage throughthe bore in which the valve-stem fits and without pinehingthe packingbetween the said valvestem and bore, and when the valve is normallyclosed the lever rests against a positive stop at the upper end of itsstroke,so as not to lessen the throw on the depression or downwardstroke needed to sufliciently open the valve; also, the constructionwhereby the valve-lever is kept steady, instead of playing loosely, asheretofore, thereby making it more agreeable to operate and facilitatingits depression in such a manner as to effect a gradual opening of thevalve and prevent sudden spurts of the liquid; also,thc constructionwhereby the packing in the valve-rod tube tightens its grip around thevalve-stem in proportion as the vertical pressure increases.

The improvement will be hereinafter fully described, and specificallypointed out in the claims,reference being had to the accompanyingdrawings, in which- Figure 1 represents a vertical section of the topand upper part of the glassof a siphonbottle constructed according to mypresent improvement. Figs. 2 and 3 are detail sections of twomodifications of the valve-stem packing.

A is the bottle, and B the ordinary glass tube reaching down nearly tothe bottom of the bottle, and through which the liquid. is pressed up tothe spout by the pressure of the gas within the bottle. The pipe B isprovided at its upper end with the usual flanged top or fitting,b,ofsoft metal, the upper end of which fits in a corresponding recess in thelower end of the top piece,G, which latter is united to.

the bottle by being threaded and screwed down upon the threaded ring a,made of two semicircular pieces which embrace the bottle-neck and areretained by the shoulder on the bottie-head, as usual. A packing-ring,1), makes a tight joint between the top piece, 0, the flanged piece I),and the upper end of the bot tle simultaneously.

In line with the glass tube B the lower end surface of the top piece,O,is provided with a. preferably spherical cavity, 0, and in the side ofthe said cavity is formed the inner end opening,n,of the spout c. i

D is the tube in which the valve rod or spindle E is arranged, as usual.The bottom of the said tube D is concave at d, where it forms a seat forthe packing of the valve-stem e, which works in a bore through thebottom of the tube from the center of the cavity (1 to the metal, andhas at its upper end, beneath its top flange, a transverse slot, d.

Iis the valve-lever, the inner part of which is of hard metal, to whichthe outer part or thumb-piece, made of soft metal, is united in thecasting. The inner end of the lever I is notched upon its upper surface,or formed in the shape of a hook, 1;, which enters acorrespondingly-madc little socket in the side of the tube D, andengages with the said notch a hard-metal pin, (1, which is secured bybeing cast in place, so that neither pin nor socket will show from theoutside of the casting. The portion 1' of the lever I, by which itengages the spindle E, is of the same height as the slot in 'which itfits, and its opposite upper and lower surfaces are curved to a radiusof half the height of the slot, so that when the leveris depressed tomove the spindle downward and open the valve F the said portion 5 willalways move ewenly and without play in the slot d.

H is the valve-stem packing. This is made of a rubber tube, as shown inFig. 2, or preferably of a hollow sphere,with diametricallyoppositeperforationsto receive the valve-stem,

as in Fig. 3. Upon the upper end surface of the said packing is placed ametallic washer, g;

fitted to move up and down slightly in the bore I 5 of the tube D. Whenthe spherical packing is er 9 is depressed against the packing H by theforce of the ordinaryspiral spring, G, which surrounds the spindle,thepacking will assume the shape shown in Fig. 1, pressing, both at its up-2 5 per and its lower end, tightly around the valvcstem e, thetightening increasing with the increase of the pressure upon thespring,as when depressing the lever I to open the valve for drawingliquid from the bottle.

The said stop z" prevents the lever from being pulled out without aspecial manipulation for the purpose. The upper end of the tube D iscovered by a cap, d as shown in Fig. 1.

In siphon-bottles as heretofore constructed the outlet or the channel tothe spout was the same as the opening through which the valvestem works,the spout-opening adjoining the said channel a distance above the valve.Above the said spout-opening the spindle was surrounded with three flatwashers, of metal,

induced a tendency to leakage through the valve-rod tube, and madenoprovision for keeping the lever steadily and firmly in contact with thespindledefects which, by my present invention, are overcome.

As samples of the state of the art previous to this application, inaddition to the patent before mentioned, I referto United States PatentN 0. 336,463; English Patents No. 2,049 of 1860 and No. 1,450 of 1882;also, French Patent No.. 25,699 of 1860; and I do not claim anythingshown in the said patents.

As shown and described in one of the above mentioned patents, EnglishPatent No. 2,049,.- it is old in siphons to employ an elasticconical-shaped valve having a flat upper surface in connection with acorrespondingly-shaped seat; but I have found by practical trial thatsuch a valve is open to the following defects: First, there is so muchof the surface of the valve tightly wedged against the wall of the sipho2 and t vea eat that; it Every soon isticks -and wedges fast secon -whennot .1sisnb ectdraws it outer-shape, so {that its keep it tight; third,when. p Z818: itimust be inorder to fit tighathe wedg; iing Preven tIfli p ti iurface-fronr touch ing the flat; valve-seat, I fourth, undersuch; I) ve the'valv'e,

A looseglobular valve free, when open, to play between two surfaces a distanceapart is impracticable for the present purpose, as it would close theinner glass tube, and thus prevent any liquid from entering the bottlewhen the siphon-bottle is inverted for filling. In order tovork'satisfactorily, it is necessary that the valve-stem betight-fitting in its bore,

while the valve must be elastic, so as to adapt itself readily to thevalve-scat opening. When the valve is elastic and globular and used incombination with the tight-fitting valve-stein threaded into the spindleE, and surrounded by the automatically-adjustable packing H,

tightening against; the said valve-stem, and

with the spiral spring G and lever I, the pressare "of the said spring(acting in connection with the elastic valve, capable of more yield-.ingor compression than what is necessary to fit it tight against itsseat) pushes the lever I always up to its absolute stop in -the slots,so

as to insure the same throw-in depressing it to open the valve. If thevalve were not elastic, the fish would be incurred that it would not beheld tight'by thespring unless the lever stop short of its-stroke orbefore reaching the stop in'the slot 8, and consequently it wouldshorten the downward throw of the lever to that extent, and thus lessenthe opening between the valve and its seat.

In Patent No. 182,612, above mentioned, the non-elastic valve used is,to a certain degree,

automatically adjustable by the valve-stem springing sidewise in thebore in whichit is loosely fitted; but in thatcase the packing pinchingit between the valve-stem and its bore, while the adjustment of the sameinthe spindle E forms'a featuremecessary, in combination with theelastic valve and packing, to

regulate the distance between the valve-seat 1 and the stop for theupper throw of the lever, to'take advantage of the elasticity of thevalve -for tightening the same without shortening the upstroke of thelever. o
